✓ Peer-reviewed alzhub usefulness score 25 out of 100. Risk genes beyond APOE

Topic: Amyloid, tau and blood-test diagnosis

La enfermedad de Alzheimer (EA) fue descrita por primera vez en una mujer, Augusta D, cuyo caso reveló las características neuropatológicas clásicas de placas amiloides y ovillos neurofibrilares. Décadas después, otro caso paradigmático, el de Aliria Piedrahita Villegas en Colombia, aportó hallazgos únicos: pese a portar la mutación PSEN1-E280A asociada a EA temprana, la presencia homocigota de APOE3 Christchurch retrasó su demencia por décadas, mostrando cómo la genética puede modificar el curso clínico. La EA afecta en mayor proporción a las mujeres, fenómeno atribuido a múltiples factores, como mayor longevidad, influencia hormonal (pérdida del efecto neuroprotector de los estrógenos tras la menopausia), variantes genéticas como APOE4 (podría conferir mayor riesgo y progresión más rápida en mujeres mayores de 65 años) y determinantes sociales, como el nivel educativo, pero todos ellos en su conjunto no logran definir todavía completamente el por qué de esta diferencia. Los biomarcadores permiten mejorar la certeza diagnostica, mostrando, en algunos casos, diferencias de sexo en niveles y patrones de patología. Comprender estas particularidades es esencial para optimizar estrategias diagnósticas, terapéuticas y de salud pública, que pueden requerir un enfoque de género, y así influir de manera positiva en la calidad de vida de las personas afectadas por EA.

Key findings

Why it matters

This review discusses why Alzheimer's disease affects women more than men, citing factors such as greater longevity, hormonal influences, APOE4, and social determinants, while noting these do not fully explain the difference. It also describes a case in Colombia where homozygous APOE3 Christchurch delayed dementia for decades despite a PSEN1-E280A mutation, but no treatment or cure is presented.
